ABAP 生成二維碼(QR Code)例子

ABAP 生成二維碼(QR Code)例子

 

1, 二維碼簡介

二維碼又稱QR Code，QR全稱Quick Response，是一個近幾年來移動設備上超流行的一種編碼方式，它比傳統的Bar Code條形碼能存更多的信息，也能表示更多的數據類型。

2, 例子代碼

網上看到一個關於二維碼的abap程序，重新整理了一下，分享給出來，供大家參考。

注意，這個例子需要能上google.com，不能上就不能顯示二維碼。。。。

完整代碼如下：

程序中需要創建一個屏幕9000，流邏輯如下：

 

1 2 3 4 5

PROCESS BEFORE OUTPUT. MODULE STATUS_9000. * PROCESS AFTER INPUT. MODULE USER_COMMAND_9000.

9000屏幕上創建一個名字為PICTURECONTROL的custom control

還要創建一個status 9000，如下：

最后Tcode smartforms 創建一個供二維碼顯示的smartform  ‘ZQR_TEST'

Form interface中創建一個輸入參數 W_NAME

Main window下創建一個Graphic，然后保存。

3, 測試顯示

選擇畫面輸入需要生成二維碼的內容，二維碼的長寬，以及顯示的模式，是abap顯示，還是smartform顯示，然后運行。

abap程序顯示如下：

Smartform顯示如下：

以上。
